4 Quick Start
This chapter lets you quickly try some of the sample applications on the SVA Kit. Details on
using scripts are provided in other chapters of this HP SVA User's Guide and other documents
in the online HP SVA Documentation Library.
4.1 Typical Uses of SVA
SVA has three primary usage scenarios as described in detail in
.
•
A workstation application that is launched remotely to use only a single node in the SVA.
•
An application that uses render and display capabilities of the SVA (for example, ParaView).
•
A workstation application that uses Chromium software and DMX to display on multiple
tiles using the SVA.
4.2 Configuring Displays for Use with SVA
There are several steps to getting the cluster display devices working, particularly in the case of
complex display systems, including stereo systems. These steps are typically done by the system
manager for the cluster.
•
Physically set up display nodes and display devices.
Plan how you want the display devices arranged, and how you want to use your display
nodes to drive your display devices. It also involves cabling the display nodes to the display
devices.
•
Configure Display Nodes and Display Surfaces.
This task involves using two SVA tools:
— Node Configuration Tool: Use this tool to define the tile orientation for individual
display nodes.
When the cluster is built by HP Manufacturing, display nodes are configured with a
default of having a single display device per display node. If a cluster uses single display
nodes to drive multiple display devices (a one to several relationship), you need to use
the Node Configuration Tool. The output of a single display node is defined as a
. The Node Configuration Tool is used when a display node drives more than one
tile, that is, uses one or two graphics cards and/or multiple ports on a card. A
is
assumed to be the image output from a single port of a graphics card.
The tool also lets you change the role of a node, for example, from render to display
and vice versa.
— Display Surface Configuration Tool: Use this tool to assemble the output of one or more
display nodes in a particular spatial orientation. This orientation is needed to define
Display Surfaces.
One or more display blocks are assembled into a Display Surface using the Display
Surface Configuration Tool.
